This draft standard is a revised version of EN 131-1:1993. Compared to the version EN 131-1:1993 the following modifications have been made: a) Further terms added in Clause 3; b) Provisions for the platform of standing step ladders added in 4.6; c) Standing ladders with both steps and rungs added as 4.7. This European Standard is one of a series about ladders. The other standards of this series are listed in Clause 2 and in the Bibliography. On stability tests and ladder classes no consensus could be reached. These issues will be addressed in the next revision.
